GAS-WASHER.

SPECIFICATION forming part of Letters Patent No. 782,011, dated February7, 1905.

Application filed June 17, 1904. Serial No. 212,973.

To (all wit/mt it may concern-.-

Be it known that l, BENJAMIN J. MULLEX, a citizen of the United States,residing at Leetonia, in the county of Columbiana and State of Ohio,have invented certain new and useful lmprovemen ts in (Itas-ll'ashers;and 1 do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to gas-washers for use in connection withblast-furnaces; and it consists in the novel construction andcombination of the parts hereinafter fully described and claimed.

In the drawings, Figure l is a vertical section through the gas-washer.Fig. 2 is a partial sectional plan view of the same.

The washingof the gas is effected in a large vessel A. The lower part Bof this vessel contains water, and l) is the outlet-pipe at the bottomof the vessel, through which the water and dirt are removedperiodically. This pipe is provided with any suitable valve 1/.

C is an overflow-pipe and water seal arranged at about the level of thewater in the washer.

The washer may be of any approved shape, and its middle part ispreferably cylindrical and its top and bottom portions conical; but itmay be of any other convenient shape.

I.) is the inlet-pipe for the. gas, which is connected to the top partof the washer and which conducts the gas into it from the blast--furnace.

E is the outlet-pipe for the gas after being washed. This pipe E isconnected to the side of the vessel A and conducts the washed gas to theboiler or stoves, where it is used in the usual way.

F is a gas-chamber which depends from the upper part of the vessel to ashort distance above the water-level, thereby forming an annular chamber1" for the Washed gas. The

lower part of the gas-chamber F is divided into a series of smallergas-chambers G, and the gas is brought in contact with the surface ofthe water it issues from these small chambers G. The small chambers Gconsist of short open-ended pipes which are secured into a head at thelower part of the gas-chamber F. The head is preferably formed of platesH, which are supported in any approved manner.

J is an angle-iron on the gas-chamber for supporting the outer portionsof the plates, and K represents pipes which depend from the upper partof the vessel A and which support the middle portions of the plates orhead.

M represents intermediate bars which also assist in supporting the.plates.

The pipes I\' afford a means for supplying the lower partof the vessel Awith water, and the water which passes through them cools them andprevents them from being destroyed by the hot gas in the upper part ofthe washer.

The gas which enters the upper part of the washer is divided up intosmall volumes before being brought in contact with the water, and thissubdivision of the gas insures the whole of it coming in contact withthe water. The gas impinges on the surface of the water as it passes outof the small chambers or pipes and parts with its dust and otherimpurities, which are taken up by the water. The clean gas passesbetween the pipes and under the bottom of the chamber F into the annularchamber-f and thence passes out by the. pipe E to the boilers or stoves.

\Vhat 1 claim is 1. In a gas-washer, the combination, with a vesselprovided with inletand outlet openings for gas, and having also anovcrllow-opening for water; of an inlet gas-chamber in the said vessel,and a multiplicity of dividing chambers or pipes supported at the lowerpart of the said gas-chamber, said dividing-chambers having open upperends which communicate with the said gas-inlet opening, and open lowerends arranged above the level of the said wateroverflow opening andcommunicating constantly with the said gas-outlet opening, whereby thegas is divided into small volumes or ets which impinge on the surface ofwater in the lower part of the said vessel.

52. In a gas-washer, the combination, with a vessel provided with anoverflow-opening for water, and having inlet and outlet openings for gasat its top and side respectively; of an inlet gas-chamber depending inthe said vessel and forming an annular space for the gas whichcommunicates constantly with the said inlet gas-cham ber depending inthe said vessel,

a head at the lower part of the said gas-chamber, water-inletsupply-pipes which support the said head from the upper part of the saidvessel, and a series of chambers suspended from the said head and havingopen lower ends arranged above the level of the said overflow-opening,said chambers operating to divide the gas into small volumes whichimpinge on the surface of Water in the lower part of the said vessel.

In testimony whereof I have affixed my signature in the presence of twowitnesses.
